Nope and yup. The juniper folk had a solution to a problem multiple
people had requested work on, and their proposal was by far the
furthest along code and use wise.
It's all fine and good making technical decisions based on drawings
and handwaving and philosophizing, but at some point someone has to do
the code. Juniper's libxo was the furthest along in implementation and
production.
It seems it is the only and final argument for libXO existence. I
remember 2 or 3 discussions against libXO spontaneously happens in the
FreeBSD lists, all ended with that, approximately: "we already have the
code and you have just speculations". Alternative and more architecture
clean ideas, like making standalone template-oriented parser probably
based on liXO, are never seriously considered, because nobody will code
it, not for other reasons.
We lack a [dtd/json] spec for tools, so programming for xo'ification doesn't
seems like the best idea in the world to me from a end-user sysadmin/developer
perspective.
I could just as easily use standard tools like awk, grep, sed, and more
advanced languages like perl or Python to parse output, and assuming output
doesn't get a major rewrite, I'd just go with that method that's worked pretty
well for me over the last 10 years of my career..
The big difference is, a json parser isn't going to blow up if a new
field gets added in the middle, and your awk/grep/sed script probably will.
Alan is exactly correct. This is EXACTLY why it is important. It
allows us to focus on the text UI without worrying about the 5000 tools
built to parse the output of the utilities. It allows us to grow a
useful text UI.
Second is that parsing is as simple as doing "json2struct()" in whatever
language you're using and then selecting a field as opposed to writing
terrible regex.
It's basically "libification" of the program without actual libification.
Next step is to actually libify the programs. Libifying the programs
would be VERY, VERY cool. But "libification" doesn't make json output
not useful.
